Whether you are a faithful follower of the goings on at NASA, such as tracking the progress of the InSight Mars Lander — or a diehard Roddenberry fan, boldly going wherever you go, you’re sure to love this rocket. The Explorer Aquarius is a skill level 4 kit that features a custom jig for perfect alignment assembly. Launched with an Estes D12-5 engine (not included), the Explorer Aquarius can fly higher than 700 feet! You’ll want to proudly display this show piece when it’s not on the launch pad, so we’ve included a removable plastic display engine nozzle for the complete effect. Challenge your modeling dexterity with this uniquely designed craft. - From the Manufacturer's Description
